Clostridium perfringens enterotoxin fragment removes specific claudins from tight junction strands: Evidence for direct involvement of claudins in tight junction barrier. (1/170)

Claudins, comprising a multigene family, constitute tight junction (TJ) strands. Clostridium perfringens enterotoxin (CPE), a single approximately 35-kD polypeptide, was reported to specifically bind to claudin-3/RVP1 and claudin-4/CPE-R at its COOH-terminal half. We examined the effects of the COOH-terminal half fragment of CPE (C-CPE) on TJs in L transfectants expressing claudin-1 to -4 (C1L to C4L, respectively), and in MDCK I cells expressing claudin-1 and -4. C-CPE bound to claudin-3 and -4 with high affinity, but not to claudin-1 or -2. In the presence of C-CPE, reconstituted TJ strands in C3L cells gradually disintegrated and disappeared from their cell surface. In MDCK I cells incubated with C-CPE, claudin-4 was selectively removed from TJs with its concomitant degradation. At 4 h after incubation with C-CPE, TJ strands were disintegrated, and the number of TJ strands and the complexity of their network were markedly decreased. In good agreement with the time course of these morphological changes, the TJ barrier (TER and paracellular flux) of MDCK I cells was downregulated by C-CPE in a dose-dependent manner. These findings provided evidence for the direct involvement of claudins in the barrier functions of TJs.  (+info)

Regulated expression of claudin-4 decreases paracellular conductance through a selective decrease in sodium permeability. (2/170)

Tight junctions regulate paracellular conductance and ionic selectivity. These properties vary among epithelia but the molecular basis of this variation remains unknown. To test whether members of the claudin family of tight junction proteins influence paracellular ionic selectivity, we expressed human claudin-4 in cultured MDCK cells using an inducible promoter. Overexpression increased the complexity of tight junction strands visible by freeze-fracture microscopy without affecting the levels of claudin-1, -2, or -3, occludin, or ZO-1. A decrease in conductance correlated directly with the kinetics of claudin-4 induction. Dilution potentials revealed that the decrease in paracellular conductance resulted from a selective decrease in Na(+) permeability without a significant effect on Cl(-) permeability. Flux for an uncharged solute, mannitol, and the rank order of permeabilities for the alkali metal cations were unchanged. A paracellular site for these effects was supported by the lack of apical/basal directionality of the dilution potentials, the linearity of current-voltage relationships, and the lack of influence of inhibitors of major transcellular transporters. These results provide, to our knowledge, the first direct demonstration of the ability of a claudin to influence paracellular ion selectivity and support a role for the claudins in creating selective channels through the tight-junction barrier.  (+info)

Expression of Clostridium perfringens enterotoxin receptors claudin-3 and claudin-4 in prostate cancer epithelium. (3/170)

The mRNA for Rvp.1 (rat ventral prostate) increases in abundance before gland involution after androgen deprivation. Rvp.1 is homologous to CPE-R, the high-affinity intestinal epithelial receptor for Clostridium perfringens enterotoxin (CPE), and is sufficient to mediate CPE binding and trigger subsequent toxin-mediated cytolysis. Rvp.1 (claudin-3) and CPE-R (claudin-4) are members of a larger family of transmembrane tissue-specific claudin proteins that are essential components of intercellular tight junction structures regulating paracellular ion flux. However, claudin-3 and claudin-4 are the only family members capable of mediating CPE binding and cytolysis. The present study was designed to study the expression of claudin-3 and claudin-4 in human prostate tissue as potential targets for CPE toxin-mediated therapy for prostate cancer. On human multiple-tissue Northern blot analysis, mRNAs for both claudin-3 and claudin-4 were expressed at high levels in prostate tissue. In normal prostate tissue, expression of claudin-3 was localized exclusively within acinar epithelial cells by in situ mRNA hybridization. Compared with expression within prostate epithelial cells in surrounding normal glandular tissue, expression of claudin-3 mRNA remained high in the epithelium of prostate adenocarcinoma (10 of 10) and prostatic intraepithelial neoplasia (five of five). Prostate adenocarcinoma cells metastatic to bone were obtained from a patient with disease progression during antiandrogen therapy. These metastatic cells were prostate-specific antigen-positive by immunohistochemical staining and also expressed functional CPE receptors as measured by sensitivity to CPE-induced cell lysis. The persistent high level of claudin-3 expression in prostate adenocarcinoma and functional cytotoxicity of CPE in metastatic androgen-independent prostate adenocarcinoma suggests a new potential therapeutic strategy for prostate cancer.  (+info)

Molecular regulation of urothelial renewal and host defenses during infection with uropathogenic Escherichia coli. (4/170)

Uropathogenic Escherichia coli (UPEC), the principal cause of urinary tract infection in women, attaches to the superficial facet cell layer of the bladder epithelium (urothelium) via its FimH adhesin. Attachment triggers exfoliation of bacteria-laden superficial facet cells, followed by rapid reconstitution of the urothelium through differentiation of underlying basal and intermediate cells. We have used DNA microarrays to define the molecular regulators of urothelial renewal and host defense expressed in adult C57Bl/6 female mice during the early phases of infection with isogenic virulent (FimH+) or avirulent (FimH-) UPEC strains. The temporal evolution and cellular origins of selected responses were then characterized by real time quantitative reverse transcriptase-PCR, in situ hybridization, and immunohistochemical analyses. Well before exfoliation is evident, FimH-mediated attachment suppresses transforming growth factor-beta (Bmp4) and Wnt5a/Ca(2+) signaling to promote subsequent differentiation of basal/intermediate cells. The early transcriptional responses to attachment also include induction of regulators of proliferation (e.g. epidermal growth factor family members), induction of the ETS transcription factor Elf3, which transactivates genes involved in epithelial differentiation and host defense (inducible nitric-oxide synthase), induction of modulators, and mediators of pro-inflammatory responses (e.g. Socs3, Cebp/delta, Bcl3, and CC/CXC chemokines), induction of modulators of apoptotic responses (A20), and induction of intermediate cell tight junction components (claudin-4). Both early and late phases of the host response exhibit remarkable specificity for the FimH+ strain and provide new insights about the molecular cascade mobilized to combat UPEC-associated urinary tract infection.  (+info)

Claudins create charge-selective channels in the paracellular pathway between epithelial cells. (5/170)

Epithelia separate tissue spaces by regulating the passage of ions, solutes, and water through both the transcellular and paracellular pathways. Paracellular permeability is defined by intercellular tight junctions, which vary widely among tissues with respect to solute flux, electrical resistance, and ionic charge selectivity. To test the hypothesis that members of the claudin family of tight junction proteins create charge selectivity, we assessed the effect of reversing the charge of selected extracellular amino acids in two claudins using site-directed mutagenesis. Claudins were expressed in cultured Madin-Darby canine kidney cell monolayers under an inducible promoter, and clones were compared with and without induction for transmonolayer electrical resistance and dilution potentials. Expression and localization of claudins were determined by immunoblotting, immunofluorescence microscopy, and freeze-fracture electron microscopy. We observed that substituting a negative for a positive charge at position 65 in the first extracellular domain of claudin-4 increased paracellular Na+ permeability. Conversely, substituting positive for negative charges at three positions in the first extracellular domain of claudin-15, singly and in combination, reversed paracellular charge selectivity from a preference for Na+ to Cl-. These results support a model where claudins create charge-selective channels in the paracellular space.  (+info)

The renal segmental distribution of claudins changes with development. (6/170)

BACKGROUND: Permeability properties of mammalian nephron are tuned during postnatal maturation. The transepithelial electrical resistance (TER) and complexity of tight junctions (TJs) vary along the different tubular segments, suggesting that the molecules constituting this structure change. We studied the differential expression of occludin and several claudins in isolated renal tubules from newborn and adult rabbits. METHODS: Isolated renal tubules from newborn and adult rabbits were processed for occludin, claudin-1 and claudin-2 immunofluorescence, and Western blot detection of claudin-1 and -2. Claudin-5 was detected in whole kidney frozen sections. RT-PCR from isolated tubules was performed for claudins-1 to -8. RESULTS: Immunofluorescence revealed that occludin, claudin-1 and -2 were present at the cell boundaries at the neonatal stage of development. Claudin-1 was detected in the tighter segments of the nephron (distal and collecting duct), while claudin-2 was found in the leaky portions (proximal). Claudin 5 was found in the kidney vasculature. PCR amplification revealed the presence of claudins-1 to -4 in tubules of newborns. In adults, claudins-1, -2 and -4 were present in proximal, Henle's loop and collecting segments; claudin-3 was in proximal and collecting tubules, while claudins-5 and -6 were absent from all tubular portions. Claudin-7 was restricted to proximal tubules, while claudin-8 was present in proximal and Henle's segments. CONCLUSIONS: The pattern of occludin distribution is present from the neonatal age. Claudins-7 and -8 are up-regulated after birth. Each tubular segment expresses a peculiar set of claudins that might be responsible for the permeability properties of their TJs.  (+info)

Changes in gene expression during the early to mid-luteal (receptive phase) transition in human endometrium detected by high-density microarray screening. (7/170)

High density cDNA microarray screening was used to determine changes in gene expression occurring during the transition between the early luteal (prereceptive) and mid-luteal (receptive) phases in human endometrium. Of approximately 12,000 genes profiled, 693 (5.8%) displayed >2-fold differences in relative levels of expression between these stages. Of these, 370 genes (3.1%) displayed decreases ranging from 2- to >100-fold while 323 genes (2.7%) displayed increases ranging from 2- to >45-fold. Many genes correspond to mRNAs encoding proteins previously shown to change in a similar manner between the proliferative and mid-luteal phases, serving as one validation of the microarray screening results. In addition, novel genes were identified. Genes encoding cell surface receptors, adhesion and extracellular matrix proteins and growth factors accounted for 20% of the changes. Several genes were studied further by Northern blot analyses. These results confirmed that claudin-4/Clostridium perfringens enterotoxin (CPE) receptor and osteopontin (OPN) mRNA increased approximately 4- and 12-fold respectively, while betaig-H3 (BIGH3) decreased >80% during the early to mid-luteal transition. Immunostaining also revealed strong specific staining for claudin-4/CPE, EP(1) and prostaglandin receptor in epithelia, and leukotriene B4 receptor in both epithelia and stroma, at the mid-luteal stage. Collectively, these studies identify multiple new candidate markers that may be used to predict the receptive phase in humans. Some of these gene products, e.g. OPN, may play direct roles in embryo-uterine interactions during the implantation process.  (+info)

Expression, solubilization, and biochemical characterization of the tight junction transmembrane protein claudin-4. (8/170)

The tight junction tetraspan protein claudin-4 creates a charge-selective pore in the paracellular pathway across epithelia. The structure of the pore is unknown, but is presumed to result from transcellular adhesive contacts between claudin's extracellular loops. Here we report the expression of claudin-4 by baculovirus infection of Sf9 cells and describe the biochemical analysis suggesting it has a hexameric quaternary configuration. We show the detergent perfluoro-octanoic acid is able to maintain oligomeric claudin species. Sucrose velocity centrifugation and laser light scattering are also used to investigate the oligomeric state of claudin-4. In contrast to proteins of similar topology, such as gap junction family connexins, the oligomeric state of claudins appears more dynamic. These data suggest the structural organization of claudins in tight junction pores is unique.  (+info)

Claudin-4 - Biocare MedicalClaudin-4 - Biocare Medical
Claudin-4 (Clostridium perfringens enterotoxin receptor) is a tight junction protein encoded by the gene CLDN4. Expression of Claudin-4 has been associated with either poor prognosis or a more favorable diagnosis, depending on the type of cancer. Claudin-4 has been shown to distinguish adenocarcinoma from malignant mesothelioma with 99% specificity in malignant effusions (1). Claudin-4 overexpression was able to independently predict survival in a breast cancer multivariate analysis as it was associated with poor prognosis, high tumor grade and Her2 expression and was inversely correlated with estrogen receptor staining (2). In luminal breast cancer, the increase of Claudin-4 protein was correlated with the increase of tumor grade and with Ki-67, and thus demonstrated an overall shorter life survival (3). Basal-like tumors also demonstrated overexpression of Claudin-4 (4). Counter to the above breast cancer subtypes, the presence of Claudin-4 in triple negative breast cancer was a biomarker that

Development of innovative, effective therapies against recurrent/chemotherapy-resistant ovarian cancer remains a high priority. Using high-throughput technologies to analyze genetic fingerprints of ovarian cancer, we have discovered extremely high expression of the genes encoding the proteins claudin-3 and claudin-4. Because claudin-3 and -4 are the epithelial receptors for Clostridium perfringens enterotoxin (CPE), and are sufficient to mediate CPE binding, in this study we evaluated the in vitro and in vivo bioactivity of the carboxy-terminal fragment of CPE (i.e., CPE290-319 binding peptide) as a carrier for tumor imaging agents and intracellular delivery of therapeutic drugs. Claudin-3 and -4 expression was examined with rt-PCR and flow cytometry in multiple primary ovarian carcinoma cell lines. Cell binding assays were used to assess the accuracy and specificity of the CPE peptide in vitro against primary chemotherapy-resistant ovarian carcinoma cell lines.

Structural insight into tight junction disassembly by Clostridium perfringens enterotoxin | ScienceStructural insight into tight junction disassembly by Clostridium perfringens enterotoxin | Science
The entire human body and its many compartments are shielded from their external environments by the barrier function of epithelial cell sheets. The paracellular barrier function of tight junctions (TJs) is critical for maintaining homeostasis in any multicellular organism, especially in the skin and internal organs and at the blood-brain barrier. One of the major components of TJs is a family of adhesive membrane proteins known as claudins. Several members of the claudin family are receptors for the bacterial toxin Clostridium perfringens enterotoxin. This toxin often causes food-borne illness both in humans and animals. Saitoh et al. crystallized a complex between the toxin and a claudin that reveals just how the toxin damages epithelial barriers (see the Perspective by Artursson and Knight)..

As mentioned in our introduction, the availability of CPE-directed therapeutics could be helpful for ameliorating several CPE-associated medical conditions. A previous study had suggested that the drug mepacrine might be a candidate CPE therapeutic because the presence of this drug interferes with CPE-induced electrophysiologic activity in artificial lipid bilayers (24). However, that study did not distinguish whether mepacrine inactivates the CPE protein or instead interferes with some step in CPE action, i.e., whether this drug affects CPE binding, CPE pore formation, or CPE pore activity. Furthermore, it was specifically important to determine whether mepacrine is not only protective against CPE electrophysiologic activity in artificial membranes but also inhibits CPE-induced cytotoxicity in mammalian cells, where receptors are present and complex phenomena like membrane vesicle release occur (30).. Therefore, a first major contribution of the current study entailed demonstrating that ...

The ability to invade host tissues and metastasize is the major cause of cancer-related death. During tumor invasion, metastasizing cells disrupt normal cell-matrix adhesion and acquire an invasive phenotype. Claudins are adhesion proteins localized at tight junctions (TJs). Claudin-7 is a unique TJ membrane protein in that it has a stronger basolateral membrane distribution than that of apical TJs in epithelial cells. To study the basolateral function of claudin-7, claudin-7 gene silencing experiments were carried out in a lung cancer cell line using the lentivirus shRNA approach. We found that claudin-7 knockdown (KD) cells showed disrupted cell-matrix interactions. Consequently, when claudin-7 KD cells were plated on the uncoated glass surface, they were unable to attach to the glass and died the day after plating. In contrast, control cells adhered well and grew normally. Using immunofluorescent microscopy and biochemistry methods, we found that claudin-7 co-localized and ...

Role of claudin-1 in colon tumor progression and metastasis - Research NebraskaRole of claudin-1 in colon tumor progression and metastasis - Research Nebraska
DESCRIPTION (provided by applicant): Disruption of the cell-cell junction with concomitant changes in the expression of junctional proteins is a hallmark of cancer metastasis and invasion. Role of adherent junction proteins have been studied extensively in cancer, however the role of tight junction proteins is less understood. Claudins are the recently identified tetraspanins, which are integral to the structure and function of tight junctions (TJs). Recent studies have shown changes in expression/cellular localization for claudins during tumorigenesis, however a cause and effect relationship has not been established. Here, we report a highly increased expression for claudin-1 in human primary colon carcinoma and metastatic tissues and cell lines derived from similar sources with relatively frequent nuclear localization. Furthermore, using genetic manipulations of claudin-1 expression in colon cancer cell lines, we demonstrate a role for claudin-1 in the regulation of epithelial to mesenchymal ...

The aim of this study was to characterize the hCMEC/D3 cell line, an in vitro model of the human Blood Brain Barrier (BBB) for the expression of brain endothelial specific claudins-3 and -12. hCMEC/D3 cells express claudins-3 and -12. Claudin-3 is distinctly localized to the TJ whereas claudin -12 is observed in the perinuclear region and completely absent from TJs. We show that the expression of both proteins is lost in cell passage numbers where the BBB properties are no longer fully conserved. Expression and localization of claudin-3 is not modulated by simvastatin shown to improve barrier function in vitro and also recommended for routine hCMEC/D3 culture. These results support conservation of claudin-3 and -12 expression in the hCMEC/D3 cell line and make claudin-3 a potential marker for BBB characteristics in vitro.

The expression of claudin-11 in benign and malignant bladder tissue and the effect of forced expression of claudin-11 on tight junction function and invasiveness of bladder cancer cells were studied. Claudin-11 expression was tested in bladder cancer cell lines (T24/83, RT 112/84 and EJ138) using reverse transcription-polymerase chain reaction (RT-PCR) and in benign and malignant bladder tissue by quantitative RT-PCR and immunohistochemistry. T24/83 cells were transfected with the pcDNA.1/NT-GFP-TOPO vector containing full-length human claudin-11 sequence. Stable-transfected cells overexpressing claudin-11 (T24Cl-11Ex), wild-type cells (T24WT) and the empty plasmid control clone (T24GFP) were compared using transurothelial resistance (TUR), in vitro adhesion, invasion and growth assays. Claudin-11 was strongly expressed in the non-invasive RT112/84 cell line compared to the invasive T24/83 and EJ138 TCC cell lines. Benign bladder tissue demonstrated equal expression of claudin-11 mRNA as ...

The transcription factors Slug and Snail act as repressors of Claudin-1 expression in epithelial cells1 | Biochemical JournalThe transcription factors Slug and Snail act as repressors of Claudin-1 expression in epithelial cells1 | Biochemical Journal
Claudin-1 is an integral membrane protein component of tight junctions. The Snail family of transcription factors are repressors that play a central role in the epithelial-mesenchymal transition, a process that occurs during cancer progression. Snail and Slug members are direct repressors of E-cadherin and act by binding to the specific E-boxes of its proximal promoter. In the present study, we demonstrate that overexpression of Slug or Snail causes a decrease in transepithelial electrical resistance. Overexpression of Slug and Snail in MDCK (Madin-Darby canine kidney) cells down-regulated Claudin-1 at protein and mRNA levels. In addition, Snail and Slug are able to effectively repress human Claudin-1-driven reporter gene constructs containing the wild-type promoter sequence, but not those with mutations in two proximal E-box elements. We also demonstrate by band-shift assay that Snail and Slug bind to the E-box motifs present in the human Claudin-1 promoter. Moreover, an inverse correlation in ...

HCV is a leading cause of hepatocellular carcinoma and cirrhosis all over the world. Claudins belong to family of tight junctions proteins that are responsible for establishing barriers for controlling the flow of molecules around cells. For therapeutic strategies, regulation of viral entry into the host cells holds a lot of promise. During HCV infection claudin-1 is highly expressed in liver and believed to be associated with HCV virus entry after HCV binding with or without co-receptor CD81. The claudin-1 assembly with tight junctions is regulated by post translational modifications. During claudins assembly and disassembly with tight junctions, phosphorylation is required at C-terminal tail. In cellular proteins, interplay between phosphorylation and O-β-GlcNAc modification is believed to be functional switch, but it is very difficult to monitor these functional and vibrant changes in vivo. Netphos 2.0 and Disphos 1.3 programs were used for potential phosphorylation; NetPhosK 1.0 and KinasePhos for

Claudin-2, a component of the tight junction, forms a paracellular water channel | Journal of Cell ScienceClaudin-2, a component of the tight junction, forms a paracellular water channel | Journal of Cell Science
Recent investigations revealed that epithelial TJs contain charge- and size-selective pores, which control the paracellular flux of charged and uncharged solutes. The paracellular flux occurs through two distinct pathways: one high-capacity pathway with size-restrictive pores and one low-capacity pathway that is size independent, at least for substances with radii of up to 7 Å (Van Itallie et al., 2008; Watson et al., 2001). The physical basis of the low-capacity pathway is not yet completely understood, whereas the high-capacity pathway is well described. It consists of small pores with radii of ~4 Å, and is responsible for the flux of small charged and uncharged solutes. Expression of claudin-2 affects only the high-capacity pathway, by inducing an increase in pore number and a change in charge selectivity (Van Itallie et al., 2008). In a recent attempt to model the claudin-2-induced channel (Yu et al., 2009), the pore diameter, calculated from permeability to organic cations and from the ...

Claudin - WikipediaClaudin - Wikipedia
Claudins are a family of proteins that are the most important components of the tight junctions, where they establish the paracellular barrier that controls the flow of molecules in the intercellular space between the cells of an epithelium. They have four transmembrane domains, with the N-terminus and the C-terminus in the cytoplasm. Claudins are small (20-27 kilodalton (kDa)) transmembrane proteins which are found in many organisms, ranging from nematodes to human beings, and are very similar in their structure, although this conservation is not observed on the genetic level. Claudins span the cellular membrane 4 times, with the N-terminal end and the C-terminal end both located in the cytoplasm, and two extracellular loops which show the highest degree of conservation. The first extracellular loop consists on average of 53 amino acids and the second one, being slightly smaller, of 24 amino acids. The N-terminal end is usually very short (4-10 amino acids), the C-terminal end varies in length ...

In this work, we assessed the effects of sinomenine (SN) on intestinal octreotide (OCT) absorption both in Caco-2 cell monolayers and in rats. We also investigated the molecular mechanisms of tight junction (TJ) disruption and recovery by SN-mediated changes in the claudin-1 and protein kinase C (PKC) signaling pathway. The data showed that exposure to SN resulted in a significant decrease in the expression of claudin-1, which represented TJ weakening and paracellular permeability enhancement. Then, the recovery of TJ after SN removal required an increase in claudin-1, which demonstrated the transient and reversible opening for TJ. Meanwhile, the SN-mediated translocation of PKC-α from the cytosol to the membrane was found to prove PKC activation. Finally, SN significantly improved the absolute OCT bioavailability in rats and the transport rate in Caco-2 cell monolayers. We conclude that SN has the ability to enhance intestinal OCT absorption and that these mechanisms are related at least in part to

Claudin-3 is a major protein of tight junctions (TJs) in the intestinal epithelium and is critical for maintaining cell-cell adhesion, barrier function, and epithelium polarity. Recent studies have shown high claudin-3 levels in several solid tumors, but the regulation mechanism of claudin-3 expression remains poorly understood. In the present study, colorectal cancer (CRC) tissues, HT-29 and DLD-1 CRC cell lines, CRC murine model (C57BL/6 mice) and c-kit loss-of-function mutant mice were used. We demonstrated that elevated claudin-3 levels were positively correlated with highly expressed c-kit in CRC tissues based upon analysis of protein expression. In vitro, claudin-3 expression was clearly increased in CRC cells by overexpressed c-kit or stimulated by exogenous recombinant human stem cell factor (rhSCF), while significantly decreased by the treatment with c-kit or c-Jun N-terminal kinase (JNK) inhibitors. Chromatin immunoprecipitation (ChIP) and luciferase reporter assay showed that SCF/c-kit

JCI - Epithelial HIF-1α/claudin-1 axis regulates barrier dysfunction in eosinophilic esophagitisJCI - Epithelial HIF-1α/claudin-1 axis regulates barrier dysfunction in eosinophilic esophagitis
Epithelial barrier dysfunction is a significant factor in many allergic diseases, including eosinophilic esophagitis (EoE). Infiltrating leukocytes and tissue adaptations increase metabolic demands and decrease oxygen availability at barrier surfaces. Understanding of how these processes impact barrier is limited, particularly in allergy. Here, we identified a regulatory axis whereby the oxygen-sensing transcription factor HIF-1α orchestrated epithelial barrier integrity, selectively controlling tight junction CLDN1 (claudin-1). Prolonged experimental hypoxia or HIF1A knockdown suppressed HIF-1α-dependent claudin-1 expression and epithelial barrier function, as documented in 3D organotypic epithelial cultures. L2-IL5OXA mice with EoE-relevant allergic inflammation displayed localized eosinophil oxygen metabolism, tissue hypoxia, and impaired claudin-1 barrier via repression of HIF-1α/claudin-1 signaling, which was restored by transgenic expression of esophageal epithelial-targeted stabilized ...

Findings: hCMEC/D3 cells express claudins-3 and -12. Claudin-3 is distinctly localized to the TJ whereas claudin -12 is observed in the perinuclear region and completely absent from TJs. We show that the expression of both proteins is lost in cell passage numbers where the BBB properties are no longer fully conserved. Expression and localization of claudin-3 is not modulated by simvastatin shown to improve barrier function in vitro and also recommended for routine hCMEC/D3 culture ...

Familial hypomagnesemia with hypercalciuria and nephrocalcinosis is an autosomal recessive tubular disorder characterized by excessive renal magnesium and calcium excretion and chronic kidney failure. This rare disease is caused by mutations in the CLDN16 and CLDN19 genes. These genes encode the tight junction proteins claudin-16 and claudin-19, respectively, which regulate the paracellular ion reabsortion in the kidney. Patients with mutations in the CLDN19 gene also present severe visual impairment. Our goals in this study were to examine the clinical characteristics of a large cohort of Spanish patients with this disorder and to identify the disease causing mutations. We included a total of 31 patients belonging to 27 unrelated families and studied renal and ocular manifestations. We then analyzed by direct DNA sequencing the coding regions of CLDN16 and CLDN19 genes in these patients. Bioinformatic tools were used to predict the consequences of mutations. Clinical evaluation showed ocular defects in

The tight junction protein claudin-1 (CLDN1) has been shown to be essential for hepatitis C virus (HCV) entry-the first step of viral infection. Due to the lack of neutralizing anti-CLDN1 antibodies, the role of CLDN1 in the viral entry process is poorly understood. In this study, we produced antibodies directed against the human CLDN1 extracellular loops by genetic immunization and used these antibodies to investigate the mechanistic role of CLDN1 for HCV entry in an infectious HCV cell culture system and human hepatocytes. Antibodies specific for cell surface-expressed CLDN1 specifically inhibit HCV infection in a dose-dependent manner. Antibodies specific for CLDN1, scavenger receptor B1, and CD81 show an additive neutralizing capacity compared with either agent used alone. Kinetic studies with anti-CLDN1 and anti-CD81 antibodies demonstrate that HCV interactions with both entry factors occur at a similar time in the internalization process. Anti-CLDN1 antibodies inhibit the binding of ...

Assessment of Glomerular Charge Selectivity in Man by Differential Clearance of Isoamylases | Clinical Science | Portland PressAssessment of Glomerular Charge Selectivity in Man by Differential Clearance of Isoamylases | Clinical Science | Portland Press
1. Glomerular charge selectivity was assessed using the ratio of the clearance of pancreatic isoamylase to the clearance of the more anionic salivary isoamylase (CPAm/CSAm) in 30 normal subjects, 14 patients with minimal proteinuria and 23 patients with heavy proteinuria due to primary glomerulopathies. Seven patients with minimal change nephropathy were studied in relapse and remission.. 2. CPAm/CSAm exceeded 2.0 (range 2.1-6.1) in all normal subjects, indicating that the normal glomerular capillary wall possesses charge selectivity at the molecular size of amylase (molecular mass 56 kDa). 3. CPAm/CSAm was significantly lower in patients with heavy proteinuria than in normal subjects or patients with minimal proteinuria. CPAm/CSAm was low in patients with minimal change nephropathy in relapse and rose into the normal range with steroid-induced remission.. 4. These data suggest that heavy proteinuria in primary glomerulopathies is accompanied by loss of glomerular charge selectivity. Remission ...

ZO-1, ZO-2, and ZO-3, which contain three PDZ domains (PDZ1 to -3), are concentrated at tight junctions (TJs) in epithelial cells. TJ strands are mainly composed of two distinct types of four-transmembrane proteins, occludin, and claudins, between which occludin was reported to directly bind to ZO-1/ZO-2/ZO-3. However, in occludin-deficient intestinal epithelial cells, ZO-1/ZO-2/ZO-3 were still recruited to TJs. We then examined the possible interactions between ZO-1/ZO-2/ZO-3 and claudins. ZO-1, ZO-2, and ZO-3 bound to the COOH-terminal YV sequence of claudin-1 to -8 through their PDZ1 domains in vitro. Then, claudin-1 or -2 was transfected into L fibroblasts, which express ZO-1 but not ZO-2 or ZO-3. Claudin-1 and -2 were concentrated at cell-cell borders in an elaborate network pattern, to which endogenous ZO-1 was recruited. When ZO-2 or ZO-3 were further transfected, both were recruited to the claudin-based networks together with endogenous ZO-1. Detailed analyses showed that ZO-2 and ZO-3 ...

immune Uncategorized PA-824, Rabbit Polyclonal to C-RAF (phospho-Thr269). The blood-epididymis barrier (BEB) is formed by epithelial tight junctions mediating selective permeability from the PA-824 epididymal epithelium. the paracellular permeability had been examined by two strategies TER and FITC-Dextran-based tracer diffusion assays. Both assays soon add up to related outcomes indicating a time-dependent disruption from the BEB differentially for the three TGF? isoforms (TGF?3>TGF?1>TGF?2) inside a TGF?-recetor-1 kinase- and Smad-dependent way. The small junction proteins claudin-1 was discovered to be decreased by the procedure with TGF?s whereas occludin had not PA-824 been affected. Epididymal epithelial cells are mainly attentive to TGF?s PA-824 through the basolateral side recommending that TGF? may impact for the epididymal epithelium through the stroma cell tradition versions the knockdown of 1 of the claudins (1 -3 -4 or -7) led to dramatically reduced transepithelial electrical level ...

The results of this study show that the amount of mobile receptor and the speed at which it diffuses varies according to its location within the cell. CD81 and claudin-1 are expressed equally in the filopodia and plasma membrane, whereas SR-BI is expressed at lower levels in the filopodia compared to the plasma membrane. We show that addition of both sE2 and sE1E2 has varying affects on both the speed and mobility of CD81 and claudin-1 and that the majority of significant effects observed for claudin-1 are observed at areas of potential cell contact. Finally, we demonstrate that addition of ITX5061 affects the diffusion coefficient of CD81 and CLDN-1 and the amount of mobile SR-BI. Furthermore, the effects on SR-BI are limited to areas of cell contact or exploratory regions. In summary, we present data which we hope will further current knowledge of the activity of these receptors in relation to their role in HCV infection ...

The Biology of Claudin 6 (Cldn6) in the Developing Mouse Lung by Felix Ruben Jimenez RondanThe Biology of Claudin 6 (Cldn6) in the Developing Mouse Lung by Felix Ruben Jimenez Rondan
The tight junctions (TJ), which are located in the apical region between epithelial and endothelial cells, regulate the paracellular diffusion of ions and small molecules and play an important role in maintaining cell polarity, cell-cell integrity, and permeability. In the lung, epithelial cells are attached by TJ structures. They provide a permeable barrier and cell communication. The loss of barrier integrity, which is maintained by the expression of claudins (Cldn), results in cellular permibilization and leads to paracellular diffusion of solutes and harmful molecules. There are 27 known Cldn homologous members in mice and human. Cldn6 is mostly expressed in embryonic stem cells and associated with the programing of epithelial cells during embryo development and lung morphogenesis. In order to test the hypothesis that Cldn6 expression affects lung morphogenesis, we analyzed the expression pattern of Cldn6 during lung ontogenesis to examine cell-specific expression pattern of Cldn6 during each

Claudin-1 (CLDN1) is a structural tight junction (TJ) protein and is expressed in differentiating keratinocytes and Langerhans cells in the epidermis. Our objective was to identify immunoreactive CLDN1 in human epidermal Langerhans cells and to examine the pattern of epidermal Langerhans cells in genetic human CLDN1 deficiency [neonatal ichthyosis, sclerosing cholangitis (NISCH) syndrome]. Epidermal cells from healthy human skin labelled with CLDN1-specific antibodies were analysed by confocal laser immunofluorescence microscopy and flow cytometry. Skin biopsy sections of two patients with NISCH syndrome were stained with an antibody to CD1a expressed on epidermal Langerhans cells. Epidermal Langerhans cells and a subpopulation of keratinocytes from healthy skin were positive for CLDN1. The gross number and distribution of epidermal Langerhans cells of two patients with molecularly confirmed NISCH syndrome, however, was not grossly altered. Therefore, CLDN1 is unlikely to play a critical role in ...

JCI - Matriptase-mediated cleavage of EpCAM destabilizes claudins and dysregulates intestinal epithelial homeostasisJCI - Matriptase-mediated cleavage of EpCAM destabilizes claudins and dysregulates intestinal epithelial homeostasis
Congenital tufting enteropathy (CTE) is a severe autosomal recessive human diarrheal disorder with characteristic intestinal epithelial dysplasia. CTE can be caused by mutations in genes encoding EpCAM, a putative adhesion molecule, and HAI-2, a cell surface protease inhibitor. A similar phenotype occurs in mice whose intestinal epithelial cells (IECs) fail to express the tight junction-associated protein claudin-7. EpCAM stabilizes claudin-7 in IECs, and HAI-2 regulates the cell surface serine protease matriptase, a known modifier of intestinal epithelial physiology. Therefore, we hypothesized that HAI-2, matriptase, EpCAM, and claudin-7 were functionally linked. Herein we have demonstrated that active matriptase cleaves EpCAM after Arg80 and that loss of HAI-2 in IECs led to unrestrained matriptase activity and efficient cleavage of EpCAM. Cleavage of EpCAM decreased its ability to associate with claudin-7 and targeted it for internalization and lysosomal degradation in conjunction with ...

Impact of Hyperosmotic Glycerol on Tighy Junction In VitroImpact of Hyperosmotic Glycerol on Tighy Junction In Vitro
The tight junction regulates passage of molecules throuth the paracellular spaces. Occludin and claudins are the specific trancmembrance protains present at the tight junction and are believed to regulate the cell barrier functions. To examine the response of the tight junction to hyperosmotic solutions, Ⅰinvestigated the effects of hyperosmotic glycerol on function and protein expression of the tight junction in ECV304 cells. Cell cytotoxicity analysis showed that the high (10%) concentration of glcerol damaged 64.1% of the ECV304 cells (p＜0.001), and this was confirmed morphologically. Treatment with 1%, 2% or 5% glyserol increased the paracellular permeability of fluorescein isothiocyanate (FITC) -labeled dextran by 4.7%, 18.7% and 29.4% (p＜0.05), respectively. In addition, exposure to glycerol at any concentration strongly reduced the expression of occludin, whereas enpression of claudin-1 was affected very slightly. These results suggest that hyperosmotic glycerol would certainly ...

  • A closer examination of isolated tight junctions uncovered two related ~22 kDa, four-transmembrane domain proteins, claudin-1 and claudin-2, with no similarity to occludin. (thermofisher.com)
  • Excitement in the tight junction field continues to rise following the recent discovery of claudins -3, -4, -5, -6, -7, and -8 and experiments suggesting that tight junctions in different tissues are comprised of different sets of claudin family proteins. (thermofisher.com)
  • To this end, MDCK C7 cells were stably transfected with either claudin-2 or claudin-10b, two paracellular cation-channel-forming TJ proteins that are not endogenously expressed in this cell line. (biologists.org)
  • Perturbation was overexpression of either claudin-2 or claudin-10b, as both form cation channels within the TJ of MDCK C7 cells, a tight renal epithelial cell line that lacks endogenous expression of these TJ proteins. (biologists.org)
  • Occludin and the sealing tight junction proteins claudin 5 and claudin 8 were downregulated and redistributed off the tight junction, whereas the pore-forming tight junctions protein claudin 2 was strongly upregulated, which constitute the molecular basis of tight junction changes. (bmj.com)
  • Clone REA751 recognizes the human claudin-3 antigen, an integral membrane protein which is a component of the claudin family of epithelial tight junction proteins. (miltenyibiotec.com)
  • Tight junction proteins claudin-2 and -12 are critical for vitamin D-dependent Ca2+ absorption between enterocytes. (semanticscholar.org)

  • In multicellular organisms, movement of ions, proteins and water is controlled by barriers known as tight junctions (TJs) formed by epithelial and endothelial cell monolayers [ 4 ]. (biomedcentral.com)
  • Several classes of claudin interact with other proteins to form tight junction and regulate permeability of TJs. (biomedcentral.com)
  • It is also observed that the expression of claudin proteins found to be differentially regulated in several cancers. (biomedcentral.com)
  • TJs are composed of at least three types of transmembrane protein -occludin, claudin and junctional adhesion molecules (JAMs)- and a cytoplasmic 'plaque' consisting of many different proteins that form large complexes. (genome.jp)
  • As the first step in understanding the physiologic functions of claudins (tight junction integral membrane proteins) in nephrons, the expression of claudin-1 to -16 in mouse kidneys was examined by Northern blotting. (asnjournals.org)
  • As the essential component of TJ, claudin family of transmembrane proteins plays a critical role in both architecture and flux control of TJ. (syr.edu)
  • Understanding self-assembly of claudin family proteins provides clues to better interpret TJ-related diseases and to find cure for them. (syr.edu)
  • These two proteins are expressed in the thick ascending limb (TAL) of Henle's loop and are involved in the paracellular reabsorption of calcium and magnesium [ 4 ]. (biomedcentral.com)
  • Although the expression of one of these proteins, claudin 1, is down regulated in most invasive human breast cancers (HBC), we have recently shown that high levels of claudin 1, characterized tumors belonging to the very aggressive basal-like breast cancer (BLBC) subtype. (biomedcentral.com)
  • As well, the exact combination of claudin proteins within a given tissue determines the selectivity, strength and tightness of the TJ [ 11 ]. (biomedcentral.com)
  • Tight junctions are composed of claudin and occludin proteins, which join the junctions to the cytoskeleton (1,2). (cellsignal.com)
  • The claudin family is composed of 23 integral membrane proteins, and their expression, which varies among tissue types, may determine both the strength and properties of the epithelial barrier. (cellsignal.com)
  • This antibody is specific for the ~ 22 kDa Claudin-2 protein and does not appear to cross-react with related endogenous proteins. (fishersci.com)
  • His team was the first to propose and demonstrate that the transmembrane claudin proteins create charge-selective pores in the tight junction and that different members of the claudin family confer different ion selectivity. (nih.gov)
